Tragic haunting photos show a diaper and white baby blanket on the ground outside a Bronx apartment building where a 5-month-old girl and her young mom plunged 15 stories Tuesday.

The horrific scene outside 2550 Olinville Ave. comes as the baby clings to life at Jacobi Hospital, where her 23-year-old mother died after the 3:38 a.m. incident, police and sources said.

Neighbors told police that the mom and baby may have been thrown from the balcony, and law-enforcement said cops have identified a potential person of interest in the incident, but no details were released.

“Please don’t do this!” a tenant told WABC News she heard a woman yelling before the resident saw something plummet to the ground.

Hours later, the baby’s diaper and blanket remained outside the building behind police tape, as cops continue to investigate.
